Abstract

Un chalumeau d'oxycoupage robuste et permettant une précision d'usinage élevée, comportant un élément de support (10) réalisé à partir d'un bloc indéformable en acier inox, et un élément de chauffe (20) fixé à demeure contre une face inférieure (19) de l'élément de support (10), lequel élément de chauffe est réalisé à partir d'un bloc massif en cuivre dans lequel sont ménagés des passages pour les fluides gazeux et le fluide de refroidissement qui communiquent directement avec les conduites correspondantes de l'élément de support (10), au moins une tuyère (30) étant positionnée avec précision dans deux alésages coaxiaux (41, 32) respectivement prévus dans l'élément de support (10) et l'élément de chauffe (20), la tuyère étant raccordée à une conduite (14.6) d'alimentation en oxygène de coupe. A robust flame-cutting torch allowing high machining precision, including a support (10) made from a non-deformable block in stainless steel, and a heating element (20) permanently fixed against a lower face (19) of the support element (10), which heating element is produced from a massive copper block in which are formed passages for gaseous fluids and which communicate directly with the corresponding conduits of the support element (10), at least one nozzle (30) being positioned with precision in two coaxial bores (41, 32) respectively provided in the support element (10) and the heater (20), the nozzle being connected to a pipe (14.6) for cutting oxygen supply.
